Itazura na Kiss (イタズラなKiss Playful Kiss?) is the popular,shōjo manga series by mangaka Kaoru Tada. Itazura na Kiss began to be serialized and published in 1991 by Shueisha through Margaret Magazine. It became successful very quickly and became the manga series that Tada became known for in Japan. The manga became so popular that two live TV series have been made so far in 1996 and 2005, with a sequel of the 2005 drama in late 2007. Despite its success, the manga was never completed due to the unexpected death of the author in a house accident while she was moving to another house with her husband and son. However the manga series continues to be published with the permission of the late artist's husband.
A drama CD series was released in 2005-2006 and a 25 episode anime adaptation aired in 2008. In an interview, the late author's husband, Shigeru Nishikawa, revealed that the manga's intended finale was to be conceptualized in the anime for the first time. Scripts regarding the plot of the anime closely followed the late author's planned ending.
On January 27, 2009, Digital Manga Publishing issued a press release announcing the acquisition of the license to publish Itazura na Kiss in English. They will be publishing the series in 12 omnibus editions; the first two are scheduled for November 2009 and March 2010, respectively..
